TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 395,863, dated January8, 1889.

Application filed December 2'7, 1887. Serial No. 259,118. (No model.)

To all whom it may concern.-

Be it known that I, OLIVER D. WOODRUFF, residing at Southington, in thecounty of Hartford and State of Connecticut, have invented certain newand useful Improvements in Tubular Lanterns; and I do declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, which form a part ofthis specification.

Myinvention relates to an improvement in that class of portable or handlanterns in which provision is made for automatically lifting the globeand the globe-carrier by means of springs for facilitating the lightingof the lantern and for purposes of general attention to it, the objectofthe present invention being to provide an improved lantern of the typespecified which shall be simple, compact, and cheap of construction,present an ornamental appearance, enable the globe to be released forlifting and restored to place with great facility and without danger ofburning the hand or fingers, and locate the lifting devices so as toprevent them from injury under ordinary usage of the lantern, which willpresent much of the appearance of the well-known tubular lantern oftrade.

Vith these ends in view my invention consists in a tubular lantern inwhich springs for lifting the globe are located entirely within the maindraft-tubes.

My invention further consists of a tubular lantern having certaindetailggjzji construction and combinations of parts, as will behereinafter described, and pointed out in the claims.

111 the accompanying drawings, Figure 1 is a view of my improvedlantern, partly in vertical central section and partly in elevation.Fig. 2 is a view thereof in transverse section taken on the line a l) ofFig. 1 and looking downward. Fig. 3 is a detached view, in plan,

of the globe-cap, the collar and the wires forming the top of theglobe-carrier, and the curved plate secured to said wires and making asecondary provision for restoring the globe to its normal position; andFi 4c is an enlarged detached view, in transverse section, showing oneof the draft-tubes and its spring-receiving tube.

As herein shown, the main draft-tubes A A are each taperedlongitudinally and enlarged and elongated transversely. Small circularspring-receiving tubes B B, located in virtually upright positions inthe inner portions of the respective tubes A A, which entirely inclosethem, are sealed at their upper and their lower ends, so as to beentirely out off from communication with the said tubes A A,whichtherefore remain unimpaired for discharging their primary function ofaffording draft for the lantern.

One way of sealing the lower ends of the tubes B B is illustrated byFig. 1 of the drawings, which shows a small cone, C, located at theinner edge of the lower end of each of the tubes A A, the lower ends ofthe tubes B B being set over the said cones, and so sealed fromcommunication with the said main drafttubes.

The inner faces of the upper ends of the tubes B B are provided eachwith a vertical slot, D, aligned with a similar slot, E, formed in eachof the tubes A A. Slightly-upturned jecting outward from the wires G Gof the globe-carrier, enter the respective tubes B B through the saidslots. The inner ends of these arms are connected with caps H H, securedto the upper ends of spiral springs I I, respectively located in thelower ends of the tubes B B, and normally contracted and eX- erting aconstant tendency to automatically lift the globe J above the burner Kof the lantern. It will be noted that in the depressed position of theglobe and globe-carrier, as shown by Fig. 1 of the drawings, these armsF F do not extend across and meet the outer walls of the tubes B B, thisconstruction being adopted to compensate for the inward inclination ofthe tubes. The said globecarrier is provided at its lower end with acentrally-perforated disk, L, adapted to set over the burner K,supporting the lower end of the globe J and attached to the lower endsof the wires G' G of the globe-carrier. The upper through slots M M,formed in the opposite edges of a cap, N, centrally perforated, so as toslide freely up and down on the vertical draft-tube O, which dependscentrally from the upper draft-tube, P, into the upper end arms F F,respectively secured to and pro-.

ends of the said wires G G respectively pass IOO of the globe. connectedthe wire spring Q, embracing the llanged upper end of the globe andprovided with a finger-loop, R, by means of whieh the spring is lit'tedfor removing and replacing the globe. The upper ends oi the said wires(T G, after passing thrmigh the slots M M in the cap N, are bent inward,as ath S, and terj minate in a eollar,'l, loeatet'l above the cap andeneireling and sliding l'reely up and down on the tube atoresaid. Thiscollar is independent of the said eap, which is lit't ed only throughthe globe, and therefore only when the same is in place.

A eurved plate,l.", connected with the bent portions 5 S of the wires(l, is provided For depressing the globe. This, however, will ehietly bedone by means of two linger-pieces, V Y, (see Fig. 2,) formed ot wireand secured to the perforated disk L and projecting hori- If desired,these lingerzontally thereli'rom. pieces may consist of extensions ofthe lower ends of the wires (i' G. The globe is main tained in itsnormalLv-del)ressed position by a eateh engaging with the lower portionol the I globe-carrier.

As herein represented, the perforated disk L is provided near one edgewith a dependin g wire loop, \V, which is engaged with a beveled bolt,X, provided at its outer end with a knurled button, Y, and horizontallymounted in a standard, Z, located upon the upper t'aee moisturewhich mayenter themthrough their vertical slots I) I).

Under the construct ion described the globe will be normally maintainedin its depressed position and against the lifting power of the sprin I Iby the en gagel nent of the depending loop \V by the beveled bolt IX.When access to the burner is desired fol-lighting the lantern or for anyother 1n.'1)ose, the knurled button of the bolt seized by the lingersand the bolt disengaged from theloop referred, to. This done, the spiralsprings I I will innnediately operate to lift the globe and theglobeearrier, and hold them both in their elevated positions. Then whenit is desired to restore the globe to its normal position it and itscarrier are drawn down by the finger-pieces \Y until the loop \V is:mtomatieally re-engaged with the beveled spring-actuated belt, which itretires for this re-engagement by first: engaging and pushing againstits beveled face. ()rdinarily the globe will be restored to its normalposition by these finger-pieces V V; butas it;

maybe sometimes more convenient to depress the globe from the top of thelantern the curved plate U is provided thereto. It is to be noted thatby locating the catch below To the lower face of this cap is l the flameit always remain eool,and there is no danger of burning the lingers inoperating it, which must; always exist when it is located above theflame, and particularly when it is arranged in connection with thevertical eentral dra'l't-tube, as has heretofore been done.

By loeat ing the spiral syn-ings T l entirely within the maindral't-t'nbes A A they are completely protected and the lantern is leftuntnie'uml)ered with expensive and unsightly attzielnnents. Moreover,the short arms 'I 11, playing in the vertical slots 1) 1), guide theglobe and the earrier in their vertital movement. 3y making the maindraft-tubes tapering a symmetrical et'l'eet is secured with abundantdral't-spaee.

iy making the globe-carrier to move independently ol' the globescap I amenabled to make both the rap and carrier very light and compact andsecure a construction at onee substantial and elegant. The cap not beingrelied upon to give stability tothe carrier is made of light stoek, olsimple term, and only large enough to tultill its function as a tap forthe globe. The deseribed eonstruetion is also very flexible andavoidsthebinding of the cap upon the tube, securing a very tree andprompt action of the carrier. The cap being made very small, the sidewires of the carrier are connected with the central draft-tube with areduction ol. leverage over old eonst'ruetions, whereby steadiness ofoperation and stability ire secured.

I am aware that it is old to locate a catch at the lower end of alantern. I do not, therefore, broadly claim that construction, but onlythe particular eombinat ion herein presented.

The Feature .herein shown of a carrier made to move independently of theglobe-cap is also shown in my application, serially numbered 26],(312,of January 23, 1889, in which, however, it is not broadly claimed, butonly in the lmrtieuhncombination therein n 'esented.

It is obvious that in earrying out my invention some changes from theconstruction herein represented maybe made. I would tiuj relore have itunderstzocufl that I do not, limit myself to the exact constructionshown. and deseribed, but hold myself at liberty to make sueh changesand alterations as fairly :t'all within the spirit and scope of myinvention.
